  • Plasma-assisted odour-free regulation of gas pressure inside stoma bag
    Patent number: 10874540
    Abstract: An ostomy pouching device is configured to allow two-way flow of gas between the device and a stoma bag (100). A check valve (104) is configured to allow ambient air into a channel of the device, and thereby into the stoma bag, when a pressure of the gas in the channel is less than a pressure of the ambient air; another check valve (105) is configured to allow gas to flow into a deodorizing reactor (110) when a pressure of the gas in the channel is greater than a pressure of the ambient air. The deodorizing reactor includes a plasma reactor configured to generate plasma in the channel for deodorizing the gas in the channel before being expelled from the device into the ambient air. The plasma reactor is preferably a dielectric barrier discharge (DBD) reactor. It may also include a secondary active carbon filter.
